Be .itknorvn that I, SANFORD BncKwITH, of lthe, cityot' Oshkosh, countyof Winnebago, and State ofWsi cousin, have invented anew and improvedSe'edngMachine; and-I do hereby declare that the following is a full andexact description thereof, reference beinghadto the 'accompanyingdrawings, 'and to the letterscf' reference marked thereon, the samemallcing a part of these speciiications, in which- Figure lisaperspectivc view. i

Figure 2 is a verticalsection.

Figure 3 is a fragment of a longitudinal section.

Figure 4 is aperspective vien.r ofthe cup m): m is a verticalse'ctiorrof fig.V 4; f is a bearing for the shaft r', figs. 2 and 5. i ll Figure 5 is-a perspective view 0fthe screw-cylinder d.; f is an-endview,'showing'the terminal shape of the screw-threads at f. l A l Af Y lt Figure 6 is a front elevation of the back or part .Zmofjthescattering-tubes.

Figure 7 is a front elevation ofthe front onpartkof the,scatteringtuhes';`l cis a vertical sect-ion of the top, l" 7c a verticalsection ofthe centre, andl"4 c" a vertical section of the bottom off thescatteringtube Ik, seen also-in figs. Zjand 3; hra-g. 6, are slotsfthatadmit of al vertical adjustment ofl Z relative to lc; nn, in lc, areea'rs with bolt-holesfor securing l and 7c to the axle a, as seen infigs. 2 and 3; ting. 6, is ahalf conical shape; the bottom horizontalshape may be seen at Z" the vertical shape maybe seen at l, figs. 2 and8. Figure 8 is a fragmental view in perspective of a s'eries ofadjustable caps or cut-offs, seen in fig. 1, and at e in figs. 2 and 3;z'zis a longitudinal sliding frame; 2" r are supports' permanentlysecured to the bottomedge of the-seed-box, and hold the sliding frame toservice.

l Figure 9 isv an enlarged view of the lag and cultivator-tooth, seeninlg. 2, with mode of adjusting and securing thetooth relative to thelag; gisa rod or metallic connection between tooth o and lagp; -Sis ahookbolt, and is the medium through which the tooth o is securedandadjusted to the rod q. E. is a view of the hook-bolt attached to afragmentrof tooth o. The outer third of the rod q is bentto a circularform, correspond ing with the radius descri-bedffrom itsconnection withthelagp bythe tooth o a is an axle; c c is a horizontal frame; b is aseed-box b is ahopper to seed-box. i

The purpose of this .invention is to provide a more uniform, reliable,and eiicient means of feeding the grain tothe scatter-er, or toaUdrill-deliveryf-and toV provide a scatter-cr that is adjustable, andthat maybe equally 'well adapted to either wheat or oats,V p Y l Thenovelty of this'invcntion consists in thel employment andadaptation ofcertain devices and their use jointly, and in combination with theseed-'b ox, shaft, and other `auxiliaries of a seeding-machine. Theshaft has its bearings on a 'framework attached to the axle beneath theseed-box. On the shaft at proper intervals, is provided a series ofscrew-cylindery seed-distributers, revolving with the shaft. The screwof thecylinder may be'double or single, and of any practical formknown,v to the nrt, or ofthe particular form represented in -thedrawings; In thelatter form, the space between threads at one end of thecylinder is of a minimum size, both as to width and depth, andgraduallyincreases in size both as to width and depth, until the. thread orthreads worm the whole length of the cylinder;` The ends Vof lthethreads are lrounded from the outer 'periphery of the cylinder tothejbott'oin of the space between threads.

Eachcylinder is provided with a cup, of a half cylindrical form, or itmay be of any other form ii'nown to the art, wherein the seed-cylindersrotate. AThe diiference in size between the diameter of the cylinder andthe inner periphery of the cup is suiiicient to obviate any possiblechancey of crushing or bruising the seed when the cylinders arerevolving. The discharge-end of'the cup may hc ofany convenient formknown to the art, that will admita discharge of the grain, or may-,be asrepresented in the drawings, wherein the cupl is notched and the endspartially moulded in towards the radial centre, in'such a form relativeto the dischargele'nd'of the screw-cylinder, that when'the cylinder isin motion, a continuous and uniform discharge of the grain will be-e'ectefL Over each cylinder are located adjustable seniieircular capsor cut-os, which, together with thev cups, encircle the cylinders. Thecaps are each secured to aparall'el frame, which in turn is held toservice by slidcbearings secured to the bottom of the'seed-box. Theparallel frame and the caps are made to slide, and are designed both tocutod entirely the'flow of grain, and are adjustable to regulate thequantity of grain sown' toda, given area. It will be noted that byreason ofthe gradual increase of the space between the screw-threads intle cylinder, andas you adjust or increase the opening of thefcap orcut-off relative to the cylinder, in-pro# portion you increase thedischarge of the grain as to quantity. It may be remarked further, thatthe scattering of grain is uniform over the area travelled, whetherthetnachine be driven quickly or moderately.

Beneath the 'seed-distributing cylinders and cups is arranged aseries oftubes or seattcrers, of a semi-` elliptcal form (horizontally.) Thelower half of the innerer adjustable partis primarily dat, but has aconical form, with a half-ellipticalshaped angc at the bottom, andaaring or hopper-shape-at thetop. The outer or stationary part, while itis of a semi-elliptical form (hcrizontally,) is largt atthe top, andthus, in conjunction with the part first described, forms a hopper.Iltis smallest in the centre, and of a medium size at the bottom,suiiicient in size, however, to leave ample space between the outerand-stationary part and the inner. or adjustaf ble part for thedischarge and scattering of the grain.

The inner partis--piovided centrally with slotted openings, that allowof avertical adjustment, and thus provides for an adjustment of thedischarge that adapts the tubes to scatter equally well, over the samearea,

wheat and oats.

The cultivator-toothis pivoted atone end of the lag. Dropping diagonallyfrom the lug is a metallic rod or brace, the outer end being bent to acircular form, to allow an adjustmentof-tle tooth. The circular pai-t ofthe brace intersects the tooth to which the same is secu-rediy ahook-bolt; the hook clasping the brace,

' holding it firmly to the tooth, and is thus secured by a nut on theopposite side ofthe tooth. By loosening the 'nutand slid-ing the tooth,it may be adjusted to any required angle,

What Iclaim asmy invention, and desire to secure by Letters Patent,is 1. The screwcylinder d, cup m, and adjustable cap c, arrangedrelatively onev to the' other for joint action, lsubstantially as andfor the purposes set forth. l

' 21 The screw-cylinder d in combination with cup m, as herein describedfor the purposes set forth.

3. The semi-elliptical tube or scatterer k Z, as and for the'purposesset forth.v 4. The'slots n n, as a means ofadjusting the part'Zirelative' to the part k, as and for the purposes set forth.
